The latest poll results are in. The question was "Have you upgraded to Leopard 10.5 yet?"
Leopard users are the majority in a landslide. There were 677 votes in all with 75% of you using Leopard right now. Another 19% said you don’t have Leopard yet, but you plan on upgrading soon.
And finally 6% said you have no plans to upgrade. I’d like to hear back from this group–why no plans on upgrading?

Thanks to everyone who participated in the poll.

I'm new to the cult of Mac and by your poll I'm in a narrow minority but is it really necessary to upgrade? Tiger works great for me now, and I doubt, however cool, not having Leopard will actually improve my performance. November 26th, 2007 at 4:09 pm

If you are interested in backing up your data (who isn't?), Time Machine is an incredible way to do it.
If things like this don't matter to you, there obviously is no reason to upgrade to Leopard, but even if the majority of the 300+ new features are minor, there are a few really big ones there. November 26th, 2007 at 5:58 pm

Interestingly a few other people seem to be having the same issue. An update is expected with 10.5.1. This thread at Apple shows a few temporary work-arounds: http://discussions.apple.com/thread.jspa?threadID=1250503&tstart=0
Changing the channels seemed to have some effect for some users. December 15th, 2007 at 9:44 pm
